Letters Patent No. 105,922, dated August 2,1870.

IMPROVEMENT 4nl( FRAMES PORl POTATO-DIGGERS .AND SHVEL-PLWB.

The Schedule referred to in these Lettera Patent and making peut 0f th Same- To all whom it may com l'rn Be in known that I, .Lunas Mumien DICK, of Buffalo, in the county of l'lrie and State of New York, have made certain new and useful Improvements in Frames for Potato-Diggers and Shovel-Flows, of which the following is a spceication. 1

Nature of the Intention.

This invention consists in the special construction and form of :the frame Ito which the digger or plowpoint is attached, as hereinafter described.

i l General Description. In thedrawin Figure 1 is a side elevation, and

Figure 2 is a plan.

A A' is the frame;

B, the beam;v

C, thelhandles; and l D, thev digger, the latter having fingers or riddlers a a', for separating the potatoes as they go over.

The beam and the frame are formed in one piece, as shown, the former curving upward high at the rear, as shown at B, so as to form a deep space at E,

for the mass of earth and vines to fall into as they pass over the top of the fingers or riddlers, and vthus prevent clogging. l

The sides A A' areparallel, and, form the'top and bottomof the frame, the latter being of greater length,'to formv the opening point running beneath l the rows.

From the extreme point an angle-bar, c, extends upto the upper side, and forms the attachment for i the ,digger-share D.

Arrintcrmediatc vertical har, ,connects the top and bottom of the frame, as shown.

O lhenovelty in my case is theconstruction and form offthe frame, having the two parallel sides A A', t-he angular face e, and cross-bar d. This consti-actionsceures the maximum of strength, with the utmost lightness and the greatest economy I0f space and form.

The frame is made bracing in therdirection of motion, while its lateral width or thickness is so small that it can be readilytnrned or inducedlto foliow the rowin all its windings.- lhe narrow width also makes it serve as a sensitive fulcrum, in guiding and turning the plow. i

vAnother important feature is the (large open space E, made by the high curve of .the beam, said spaee'allowing the potatoesto be thoroughly sifted as they fall, and enabling the vines to clear. The narrow frame facilitates this action.

. This construction of the frameis as applicable to shovel-plows as to potato-diggers.

What I claim as my invention is-'- The construction of theframe with the parallel sides A A', the bar c, and cross-bar d, and having the beam formed in a single piece therewith, in thc manner and for the-v purpose herein described. y

In witness whereof I have hereunto signed my name in the presence of-.two subscribing witnesses. y l
